Fett-Kürnchen im Inneren, beobachtete ich im Endoplasma auf 

 Schnitten eigenthümliche canalformige Vacuolen [Fig. 2). Dieselben 

 verlaufen in verschiedener Tiefe des Endoplasmas und in verschiede- 

 nen Richtungen, etwas wellenartig gewunden; manchmal sieht man, 

 daß solch ein Canal sich umbiegt und in umgekehrter Eichtung fort- 

 läuft. Die Zahl der Canale ist sehr beträchtlich, so daß das Endo- 

 plasma manchmal wellenartig gestreift aussieht; ihr Lumen ist sehr 

 verschieden, so daß man einige derselben kaum bemerkt. Daß die 

 Canale in irgend welcher Beziehung zu den gewöhnlichen gerundeten 

 Vacuolen ständen , habe ich niemals mit Sicherheit gesehen. Gegen 

 die Vermuthung, daß es nicht Vacuolen, also Flüssigkeit enthaltende 

 Räume, sondern Ausscheidungen irgend einer durchsichtigen contrac- 

 tilen Substanz seien, spricht nach meiner Ansicht der Umstand, daß sie 

 oft ihre Richtung ändern ; wie ich schon bemerkt habe, biegen sie oft 

 um und laufen in entgegengesetzter Richtung weiter. Die Contraction 

 solcher Gebilde möchte also für den Organismus keinen bestimmten 

 Zweck haben. (Schluß folgt.)

18th June, 1895. — The Secretary read a report on the additions 

 that had been made to the Society's Menagerie during the month of May, 

 and called particular attention to the following animals: — a Blackbilled 

 Sheathbill, captured at sea, 52° S. , 55° W. , and presented by Mr. John 

 Gunn; a female Grysbok, presented by Mr. J. E. Matcham, of Port Eliza- 

 beth, South Africa : and a young male Panolia Deer, from Southern China, 

 presented by Mr. Julius Neumann, C.M.Z.S. — Mr. Sclater exhibited and 

 made remarks on the head of a Barbary Sheep [Ovis (raffelap/itis), obtained 

 by the late Capt. Dunning on the Nile above Wady Halfeh , and the skin of 

 a Humming-bird [Anthocephala Berlepschi) ixoxa. Columbia, received from 

 Mr. R. B. White, C.M.Z.S, — Prof. Howes exhibited and made remarks 

 on the skull of a Rabbit showing abnormal dentition. — A letter was read 

 from Dr. Hubrecht, F.M.Z.S., showing that a supposed new mammal from 

 Sumatra, which he had described as Trichomanis Hoevenii, was probably noth- 

 ing more than an Arctomjx. — Mr. Sclater exhibited and made remarks 

 on a specimen of Loder's Gazelle [Gazella Loderi) , recently obtained in the 

 western desert of Egypt. — Mr. W. Saville Kent exhibited a drawing of a 

 Nudibranch from Western Australia , remarkable for its large size and bril- 

 liant colour. — Mr. J. Graham Kerr read a paper on some points in the 

 anatomy of Nautilus pompilius. He described the perivisceral cavity, drawing 

 attention to the large development both of coelom and haematocoele, the 

 headward section of the body-cavity containing the crop, vena cava, etc. 

 belonging to the latter. The coelom consisted of two chambers — a genital 

 and a pericardial — separated from one another by a perforated septum. 

 The latter opened to the exterior through the viscero-pericardial pores, which, 

 together with their adjacent renal sacs , represented the pair of nephridia of
